I'm designing the propane setup for my new build. I'm installing a Dickinsen Sig 9000 propane fireplace and an Suburban two burner stove. The Dickinsen manual says to use and individual regulator for each appliance. I see the beauty in this but I guess it means I can't have my auto switching Camco dual stage regulator. which switches between tanks. Frankly I'm not sure how to design this so that I don't have to go out and swap out tanks.

"NOTE: Each low pressure propane appliance should have its own low
pressure regulator and fuel supply line as shown on the propane locker
diagram on pg. 9.

Reasons for having a separate low pressure regulator for each appliance:

1. The ABYC Standards state- 1.7.2  Each appliance shall be served by a
separate low pressure regulator and supply line that shall originate inside the
cylinder locker. We recommend you follow the ABYC standard.

2. The regulator only serves a very low pressure of gas, through a small 3/8
gas line, and depending on the distance, 1 regulator for 2 appliances
may starve the burners of gas for 1 appliance.

3. Some older appliances do not have thermocouples on the burners, and if the
gas valve on that appliance was left in the on position, gas would leak while
using the heater or any other appliance and could result in a serious explosion. "

Some appliances require lower than 11" water column...and some require the 11"

From the factory you have the regulator at the tank (11") and the stove has its own second stage drop regulator under the stove top. That is universal, as far as I know. I don't know anything about your fireplace, but I suspect it is the same situation. The furnace, fridge and water heater still need 11".
